I currently have a Jung Regulator PCB made by AOS. Is it possible to modify it to output 5V without significantly altering the board? In the schematic (here: http://www.aoselectronics.com/gfx/jsr/jung_pos.gif), you can see that the reference voltage is 6.9V, so that clearly would have to be dropped below 5V for a 5V output. Any ideas?
